The present inventionconsists of a device a for preventing theaccidental toppling over of chairs, stands and the like and one of theobjects of the invention is to provide a device which willoperate'automatically and instantaneously when said chalr or the like istilted.

- According to this invention, the improved device comprises a propwhich is arranged to be easilyattached to an ordinary chair, g forexample, particularly an infants high chair but the invention may,however, be

I used with advantage for other articles such as smoking stands.Furthermore, in some instances, it may be desirable to employ sev- 'eralprops, one on each side, if desired, so as tosupport the chair or thelike in either a side, back, or front tilted position,

The invention will .be hereinafter more fully described with referenceto the acoom panying drawings, wherein Figure 1 is a perspective viewshowing the improved device asapplied to an infants' high chair, and

Figure 2 is a side elevation showing the improved device and a part iofthe chair.

Referring toisaid drawings, the article to be supported in this caseisflan infants high chair 1 having a back2, seat 3 and legs 4. lheauxilliary support or prop for the chair comprises a pair of parallelbars 5 which are united by tie bars 6' so as to provide aIrigid-structure, Said prop is hinged at! to the plate 8 which, in turn,ispreferably "secured to the back' 2 of the chair. Said hinge 7 hasthespring 9 .associatedtherewith so as to form aniordinary spring hinge.afIn'Figure 1 of the drawingslthe supporting prop'is shown as being init's open position and inFigure' 2, in its closed position. ln'theclosed position, thefspring 9 is under tension andrthereis, therefore,atendency for the spring to throw the prop outwardly.

The prop is, however,- held in its closed po 'sition byflmeans ofthepawl lOwhich is pivotally mounted, preferably on the un- I e and,meanscomprising a spring normally,

derside of'a fixed member "of the chair, such as theboard 11. Aspring12tends to hold the pawl 10 downwardly so that the notch 13 at theendrthereof engagesthe lowermost carrying out the, details of'theinvention within the terms, of the tie bar 6.-

tripl lis carried by or connected with said pawl and arranged so that ythe extended foot 15 thereof; will lie'in the 1 same plane as the end ofthe legs 'l 6" of the chair; It is requiredfthat the prop,'when inbraced and for this purpose, the pivoted folding brace member. 17iseniployed. 'Tliis; member is bentfso as to. provide an intermediate orstraight portion 18 and legs 19 lying at right angles tosaid straightportion. The latter portionpasses through elongated slots 20, one ineach of said parallel bars Withthis arrangement, th'ebra'ce will open toits fullest extent to firmly brace the propin its'operative position anddue to the length of the slots 20, the brace will fold up againsttheback of theflchair along with therprop. N In the operation of theimproved device,

it will be understood that the foot of the trip, device 146, being in]the same plane as the end of therear legsof the chair, it is onlyrequired that the chair'should be tilted slightly in a backwarddirection when the 5 7 hereinbefore described but it is tobe under stoodthat any modificationcoming fairly appended claims shall be coveredthereby, r r V g Iclaim- 'lfA supporting means-"for chairs, stands orthelike comprising an auxiliary spring operated-leg or prop; means comprsing a latch for retaln ngjsaid leg or prop in its I closed position; atrippin g'fmeans for releasing said, latch operating,automatically undertension for throwing saidgleg or prop 111 136 its open or supportlngposltlon.
